I've wanted to see Vietnam for as long as I can remember.
What better way than by motorcycle?

I have the bike rental thing figured out.
Rent bike in Hanoi and drop it off in Saigon (HCMC) for shipment back.

I've already decided I'm going to do it, starting in December 2013.
What I'm really looking for in this thread is a little advice.

I want to see both high country and beaches along the way.
I've done some research on possible routes and read ride reports from those who have done similar.

I'm still looking for informed answers to a lot of questions, though.

For example...

Am I foolish to attempt this solo? I don't speak any Vietnamese.
Hiring a guide is possible, but maybe more hindering than helpful?

Is it possible to do this mostly on pavement?
I'm weak in the dirt
It's not clear to me from looking at maps so far which roads are paved, or not.

Is it realistic to think I can cruise into towns along the way and find a place to sleep without reservations?

I would love to have route suggestions.

Where can I expect mandatory water crossings?
I understand highway 1 along the east coast is crazy with traffic and trucks - 15 preferable?
I prefer back highways whenever possible - just not goat trails
